When stepping int myFunc(std::string a, std::string b, std::string c) I always have to work through the standard library code constructors. I have in my options "Enable Just My Code" but nothing i do seems to keep this from happening.

Todd James 0

My func definition --> int mYFunc(std::string aString, std::string aComparator, std::string aCompareValue);

Calling mYFunc("A String with Status=", "stristr", "Status=");

Standard routines I keep having to work through.

_CONSTEXPR20 basic_string(In_z const _Elem* const _Ptr) : _Mypair(_Zero_then_variadic_args_t{}) {

    _Construct<_Construct_strategy::_From_ptr>(_Ptr, _Convert_size<size_type>(_Traits::length(_Ptr)));

}

According to the documentation, if the symbols are loaded, its considered "user code" - so this facility is somewhat at odds with the facility to load symbols from a symbol server.

For code stepping behavior, Just My Code in C++ considers only these functions to be non-user code:

Functions for which the corresponding PDB file hasn't been loaded in the debugger.

Functions specified in *.natjmc files in the %VsInstallDirectory%\Common7\Packages\Debugger\Visualizers folder.

In my copy of VS2022 17.12.4 when "Enable Just My Code" is checked the debugger does not step into the constructor for a string object when a literal is passed into MyFunc. Update: Same in VS2019 16.11.43 -- debugger does not step into std::string constructor.
